This was confirmed by Mike W8LID a year or so ago via a long twitter conversation and confirmation by MC team. I personally would not run 100W through the filter but some reasonable low power level will work fine.Confirmed on past AMSAT-BB discussions in the past. Adrian AA5UK

And you can put WAY more than 0.5w through these. I have, as many others have. On Wed, Jun 9, 2021 at 6:42 PM Brian Wilkins ko4aqf@gmail.com wrote:
Herb I know you said BPF. A lot of us use the BLP-200+ LPF from Mini Circuits on the 2m side to help with desense https://www.minicircuits.com/WebStore/dashboard.html?model=BLP-200%2B

Mini-Circuits makes some SMT filters. The downside is that they're SMT with small solder pads. The other thing is, they are power limited to 0.5W.

You can buy them individually from Mouser or Digikey, and I'm pretty sure you can order *free* samples of them from Mini-Circuits.
You can buy breakout PCBs for them from ebay, for example (the boards use SMA connectors): https://www.ebay.com/itm/401190029762?hash=item5d68ca09c2:g:SmQAAOSw4shX3IVv
The downside is that they're SMT with small solder pads. The other thing is, they are power limited to 0.5W. They offer other types of bandpass filter, but I haven't done an exhaustive search... I've used them for the receive end, they work as advertised.
